re: Malapropism in Windows Calculator Accessory Sunday, March 10, 2002 at 1:29 pm Posted by Mrs. Bagley (277 messages posted) The Gradient Theorem: Let f(x,y,z), a scalar field, be defined on a domain D in R3. Assume that f(x,y,z) has linear approximations on D (i.e. is continuous on D)Then at each point P in D, . . . Perhaps the"gradients" is in there for those who are advanced enough to figure out what to do with the gradient theorem. Me? I know third grade math. Smiling.

I am still trying to figure out what I am misreading in the equation. x times x plus 2x plus 24=0 subtract 24 from each side of the equation. x squared + 2x = 24. Get get rid of the 2 by dividing 2x and 24 by the two. Now I have x squared + x =12. And that = 3. My grade = F Laughing out Loud.

This is the bit where your error is. Dividing by 2 gives you: (x squared) / 2 + x = 12 Not that that helps particularly. solution (Using Quadratic formula): x squared + 2x - 24 = 0 x = (-2 +- sq. rt. ((2*2) + (4 * 1 * 24))) / 2 x = (-2 +- sq. rt. (100)) / 2 x = (-2 +- 10) / 2 2 solutions: x = 4, x = -6. Also, ... x squared + 2x - 24 = 0 reduces to, (x - 4)(x + 6) = 0 therefore yielding 2 solutions : x = 4 or x = 6. (I feel like I'm at school again...)
